Commentary
This is a full-auto player that allows you to easily play back records just by operating the lever.
Complete automatic performance is possible by placing the record on the turntable, adjusting the rotation speed of the speed switching knob to the record, setting the record size selector to the size of the record board, and pulling the control lever toward Start.
Also, in the case of manual performance, you can do it by operating the arm by hand without pulling the operation lever.
If you push the control lever toward Stop during a performance, the arm automatically returns to the cradle and stops rotating.
The turntable is die-cast with a diameter of 30 cm.
The drive section uses a belt drive system that uses a precision processed polyurethane belt and a 4-pole synchronous motor.
Uses a universal tone arm that can be used to replace cartridges other than dedicated ones.
The needle pressure can be applied accurately with the direct reading scale.
In addition, the optimum amount for canceling the inside force can be selected by increasing or decreasing the weight to the scale position according to the needle pressure.
A decorative plate with an overhang indicating point is provided to indicate the optimum position of the needle tip.
The cartridge uses Technics280C which is a MM type cartridge.
The dust cover is a free top type that stops at any angle, and it can be put on and taken off.
The bottom of the panel is equipped with butyl rubber and an audio insulator to prevent the howling phenomenon.
